I have an issue which i believe to be electric related:
96 honda passport 3.2L v6 4x4

when i try to start the vehicle, the starter grinds on the flywheel and does not turn the motor over, almost as if it is not completely engaging. I have done little testing and found that if i allow the fuel pump to pressurize and turn off before turning to "start" there is no grind and the motor starts, i have tested this many times.

anyone have any suggestions on what I could do to fix this?

my thoughts are the dc resistance between the battery and starter is more than battery to fuel pump, therefore causing the starter to not receive enough power when needed.

if you agree with the above, then wire replacement?

more detail upon request!! suggestions?

is it a grinding or a sorta high pitched hum?

sounds just like when you have the motor running already and hit the starter...grind

could be a f'd up fly wheel, teeth on that could be ground off a lil not allowin the starter to catch unless it hits the right spot. had that happen on a work truck about 6 months ago

why would it consistently start if i allow the fuel pump to shut off?

so if u allow the fuel pump to shut off, when its starts up does it still make the grinding?

absolutely no grinding after the fuel pump shuts off.....that is why I think it is power related

i dunno why the fuel pump would have anything to do with it, i wouldn't think it could draw enough current to affect the starter...strange maybe it's something else that draws current at first. either way, i would say flywheel or starter except for the fuel pump part

Unplug the fuel pump and take a meter reading from there. Make sure your terminals are clean and tight. It should be within 0.5 volts of your battery voltage while the pump is pressurizing. Faulty electrical is the only thing I can think would be causing this since the starter doesn't, in any other way, connect to the fuel pump.

could also be your fuel pump on the way out, they make a loud hum when there tryin to build pressure but can't

FSU or FPR is not cooperating. Sounds like it's taking longer than it should for the proper fuel pressure to build up, inhibiting the engine from starting. You're idea is also a possibility. Throw some new battery cables on it, just to see. They're cheap, and it can't hurt to have new ones anyways. If you take it offroad, which I assume you do by your ava, then the cables may be soaked. Water and other contaminants can get inside them pretty easily, and mess them up.
